An ICIM-CI Model for Mass Production Development Considering Manufacturing Variations

An ICIM-CI model of an analog circuit with a differential amplification for mass production development is proposed. It is observed that manufacturing variations, such as in terms of the oscillation frequency, cause differences in failure thresholds, obtained by the DPI method, between samples. The maximum difference is 8.7 dB at 1.0 MHz. To predict the lowest forward power that causes failure, a prediction formula based on design information is obtained. By comparing the prediction results with measurements, it is confirmed that the forward power can be estimated within the range of variations.
